摘要:
Remote installation of an update of software is forwarded by a management information system into a remote computer. When a primary communication path between the management information system and the remote computer is unavailable and an alternate communication path is available, a connection is established between the management information system and the remote computer using the alternate communication path. The management information system requests from the remote computer the current version information about the software within the remote computer. When the management information system determines the current version of the software within the remote computer needs to be updated, the management information system determines whether the alternate communication path is adequate for downloading the update of the software. When the management information system determines that the alternate communication path is adequate for downloading the update of the software, the update of the software is downloaded from the management information system to the remote computer.
摘要:
A paging accessory (10) for portable computing devices (12) such as calculators, electronic notebooks, calendars or the like. The paging accessory (10) includes a board (14) on which are mounted a receiver (32) for receiving page signals and a microprocessor (34) for identifying and decoding a page signal intended for the accessory (10). The board (14) includes connectors (16) for inserting the accessory (10) into a port (15) of a portable computing device (12). Alternatively, receiver (32) may be incorporated directly into a device (12). The device (12) is programmed to compare information in its memory. For example, it can compare a received phone number against a list of phone numbers to identify the person to be called in response to the page.
摘要:
Embodiments of reflecting non-visible light off one or more mirrors are disclosed. In an embodiment, non-visible light may be reflected off of one or more mirrors in an off positon and a portion of a screen may be illuminated with the non-visible light. Other embodiments are also disclosed.

A display system includes a single image-projection device, and a reflective surface optically coupled to the image-projection device, wherein the reflective surface is configured to reflect a plurality of images projected by the image-projection device onto a plurality of display surfaces, the projection being along a same path as a collection of the plurality of images.
摘要:
An enhanced desktop management interface within a computing device interfaces with a management information system. The enhanced desktop management interface includes a service layer which has a management interface and a component interface. A plurality of management applications interact with the management interface of the service layer. Also, a plurality of manageable elements interface with the component interface of the service layer. When a primary communication path interface is available, the enhanced desktop management interface communicates with the management information system through the primary communication path. When the primary communication path interface is not available and an alternate communication path interface is available, the enhanced desktop management interface communicates with the management information system through the alternate communication path.
摘要:
The apparatus allows the connection of two peripherals to a host device through one port and switching between them. The apparatus includes a sensor for sensing a data signal from the second peripheral device and a switch responsive to the sensor. The switch in a default, first state connects the first peripheral device to the host device and in a second state disconnects the first peripheral device therefrom. If a second peripheral device is connected to the apparatus, the sensor senses a data signal from the device and communicates this sensing to the switch. The switch responds by disconnecting the first device from the host device, leaving the second device solely connected to the host device. If the second peripheral device is disconnected from the apparatus, the switch reconnects the first peripheral device to the host device.
摘要:
Apparatus that enables an optical transceiver (14) to communicate data as a bar code reader or by way of modulated light. A lens assembly (22) adjusts the focal distance of the optical transceiver (14) to enable it to communicate in these multiple modes. A control circuit (16) and microprocessor (12) are coupled to the optical transceiver (14) and are responsive to the focal distance setting of the lens assembly (22) for selecting the appropriate communication mode. The apparatus is of particular value in low-power, portable environments, such as in calculators or other portable computing devices.
